User Equipment, Network Nodes and Methods in a Wireless Communications Network

ABSTRACT

The first network node then manages (802) the configuration of neighbouring cells, based on the received configuration.

BACKGROUND

In a typical wireless communication network, wireless devices, also known as wireless communication devices, mobile stations, stations (STA) and/or User Equipments (UE), communicate via a Local Area Network such as a WiFi network or a Radio Access Network (RAN) to one or more core networks (CN). The RAN covers a geographical area which is divided into service areas or cell areas, which may also be referred to as a beam or a beam group, with each service area or cell area being served by a radio network node such as a radio access node e.g., a Wi-Fi access point or a radio base station (RBS), which in some networks may also be denoted, for example, a NodeB, eNodeB (eNB), or gNB as denoted in 5G. A service area or cell area is a geographical area where radio coverage is provided by the radio network node. The radio network node communicates over an air interface operating on radio frequencies with the wireless device within range of the radio network node.

Specifications for the Evolved Packet System (EPS), also called a Fourth Generation (4G) network, have been completed within the 3rd Generation Partnership Project (3GPP) and this work continues in the coming 3GPP releases, for example to specify a Fifth Generation (5G) network also referred to as 5G New Radio (NR). The EPS comprises the Evolved Universal Terrestrial Radio Access Network (E-UTRAN), also known as the Long Term Evolution (LTE) radio access network, and the Evolved Packet Core (EPC), also known as System Architecture Evolution (SAE) core network. E-UTRAN/LTE is a variant of a 3GPP radio access network wherein the radio network nodes are directly connected to the EPC core network rather than to RNCs used in 3G networks. In general, in E-UTRAN/LTE the functions of a 3G RNC are distributed between the radio network nodes, e.g. eNodeBs in LTE, and the core network. As such, the RAN of an EPS has an essentially “flat” architecture comprising radio network nodes connected directly to one or more core networks, i.e. they are not connected to RNCs. To compensate for that, the E-UTRAN specification defines a direct interface between the radio network nodes, this interface being denoted the X2 interface.

Multi-antenna techniques may significantly increase the data rates and reliability of a wireless communication system. The performance is in particular improved if both the transmitter and the receiver are equipped with multiple antennas, which results in a Multiple-Input Multiple-Output (MIMO) communication channel. Such systems and/or related techniques are commonly referred to as MIMO.

In addition to faster peak Internet connection speeds, 5G planning aims at higher capacity than current 4G, allowing higher number of mobile broadband users per area unit, and allowing consumption of higher or unlimited data quantities in gigabyte per month and user. This would make it feasible for a large portion of the population to stream high-definition media many hours per day with their mobile devices, when out of reach of Wi-Fi hotspots. 5G research and development also aims at improved support of machine to machine communication, also known as the Internet of things, aiming at lower cost, lower battery consumption and lower latency than 4G equipment.

NR Architecture

New Radio (NR), a.k.a. 5G or Next Generation, architecture is being discussed in 3GPP and the current concept is illustrated in FIG. 1, where eNB denotes LTE eNodeB, gNB and ng-eNB (or evolved eNB) denote NR BSs (one NR BS may correspond to one or more transmission/reception points), and the lines between the nodes illustrate the corresponding interfaces which are under discussion in 3GPP. FIG. 1 depicts NR architecture from 3GPP TS 38.300, v. 1.0.1.

Further, FIG. 2 illustrates NR deployment example scenarios with NR BS which are discussed in 3GPP. The examples relate to Non-centralized, Co-sited, Centralized and shared NR deployment.

Multi-Antenna Schemes in NR

Multi-antenna schemes for NR are currently being discussed in 3GPP.

For NR, frequency ranges up to 100 GHz are considered. It is known that high-frequency radio communication above 6 GHz suffers from significant path loss and penetration loss. One solution to address this issue is to deploy large-scale antenna arrays to achieve high beamforming gain, which is a reasonable solution due to the small wavelength of high-frequency signal. Therefore MIMO schemes for NR are also called massive MIMO. For around 30/70 GHz, up to 256 Tx and Rx antenna elements are assumed. Extension to support 1024Tx at 70 GHz is agreed and it is under discussion for 30 GHz. For sub-6 GHz communication, to obtain more beamforming and multiplexing gain by increasing the number of antenna elements is also a trend.

With massive MIMO, three approaches to beamforming have been discussed: analogue, digital, and hybrid (a combination of the two). The analogue beamforming would compensate high pathloss in NR scenarios, while digital precoding would provide additional performance gains similar to MIMO for sub-6 GHz necessary to achieve a reasonable coverage. The implementation complexity of analogue beamforming is significantly less than digital precoding since it is in many implementations relies on simple phase shifters, but the drawbacks are its limitation in multi-direction flexibility (i.e., a single beam may be formed at a time and the beams are then switched in time domain), only wideband transmissions (i.e., not possible to transmit over a subband), unavoidable inaccuracies in the analogue domain, etc. Digital beamforming (requiring costly converters to/from the digital domain from/to IF domain), used today in LTE, provides the best performance in terms of data rate and multiplexing capabilities (multiple beams over multiple sub bands at a time may be formed), but at the same time it is challenging in terms of power consumption, integration, and cost; in addition to that the gains do not scale linearly with the number of transmit/receive units while the cost is growing rapidly. Supporting hybrid beamforming, to benefit from cost-efficient analogue beamforming and high-capacity digital beamforming, is therefore desirable for NR. An example diagram for hybrid beamforming is shown in FIG. 3. Beamforming may be on transmission beams and/or reception beams, network side or UE side.

Beam Sweeping

The analog beam of a subarray may be steered toward a single direction on each OFDM symbol, and hence the number of subarrays determines the number of beam directions and the corresponding coverage on each OFDM symbol. However, the number of beams to cover the whole serving area is typically larger than the number of subarrays, especially when the individual beam-width is narrow. Therefore, to cover the whole serving area, multiple transmissions with narrow beams differently steered in time domain are also likely to be needed. The provision of multiple narrow coverage beams for this purpose has been called “beam sweeping”. For analog and hybrid beamforming, the beam sweeping seems to be essential to provide the basic coverage in NR. For this purpose, multiple OFDM symbols, in which differently steered beams may be transmitted through subarrays, may be assigned and periodically transmitted. FIG. 4 depicts Transmission (Tx) beam sweeping on 2 subarrays, and FIG. 5 depicts Tx beam sweeping on 3 subarrays.

Synchronization Signal (SS) Block Configuration

Herein is described, a non-limiting example if SS block and SS burst configuration which may be assumed in other embodiments. The signals comprised in SS block may be used for measurements on NR carrier, including intra-frequency, inter-frequency and inter-RAT (i.e., NR measurements from another RAT).

SS block (may also be referred to as SS/Physical Broadcast Channel (PBCH) block or SSB): NR—Primary Synchronization Signal (PSS), NR—Secondary Synchronization Signal (SSS) and/or NR-PBCH may be transmitted within an SS block. For a given frequency band, an SS block corresponds to N Orthogonal Frequency Division Multiplexing (OFDM) symbols based on one subcarrier spacing (e.g., default or configured), and N is a constant. UE shall be able to identify at least OFDM symbol index, slot index in a radio frame and radio frame number from an SS block. A single set of possible SS block time locations (e.g., with respect to radio frame or with respect to SS burst set) is specified per frequency band. At least for multi-beams case, at least the time index of SS-block is indicated to the UE. The position(s) of actual transmitted SS-blocks may be informed for helping CONNECTED/IDLE mode measurement, for helping CONNECTED mode UE to receive DL data/control in unused SS-blocks and potentially for helping IDLE mode UE to receive DL data/control in unused SS-blocks.

SS burst: One or multiple SS block(s) compose an SS burst. The maximum number of SS-blocks, L, within SS burst set may or may not be carrier frequency dependent, e.g.:

The maximum number of SS-blocks within SS burst set, L, for different frequency ranges are

-   -   For frequency range up to 3 GHz, L is 4     -   For frequency range from 3 GHz to 6 GHz, L is 8     -   For frequency range from 6 GHz to 52.6 GHz, L is 64

SS burst set: One or multiple SS burst(s) further compose an SS burst set (or series) where the number of SS bursts within a SS burst set is finite. From physical layer specification perspective, at least one periodicity of SS burst set is supported. From UE perspective, SS burst set transmission is periodic. At least for initial cell selection, UE may assume a default periodicity of SS burst set transmission for a given carrier frequency (e.g., one of 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms). UE may assume that a given SS block is repeated with a SS burst set periodicity. By default, the UE may neither assume the gNB transmits the same number of physical beam(s), nor the same physical beam(s) across different SS-blocks within an SS burst set. In a special case, an SS burst set may comprise one SS burst.

For each carrier, the SS blocks may be time-aligned or overlap fully or at least in part, or the beginning of the SS blocks may be time-aligned (e.g., when the actual number of transmitted SS blocks is different in different cells).

(Note that the final terminology captured in 3GPP technical specifications for the SS block concept may be not exactly the same as in this section, since the first NR specifications are not yet ready.)

FIG. 6 depicts an Example configuration of SS blocks, SS bursts and SS burst sets/series.

All SS blocks within a burst set are within 5 ms window, but the number of SS blocks within such window depends on the numerology (e.g., up to 64 SS blocks with 240 kHz subcarrier spacing).

Based on SS blocks, the UE may perform cell identification, radio measurements, RLM, system information reading, etc. A UE receives

-   -   intra-frequency SS blocks and performs corresponding         intra-frequency operations for serving cell(s) and         intra-frequency neighbour cells (in carrier aggregation or dual         connectivity the UE may have one or more serving cells), and     -   inter-frequency SS blocks and performs corresponding         inter-frequency operations for inter-frequency neighbour cells.

The intra- and inter-frequency measurements are defined as follows:

-   -   SSB based intra-frequency measurement: A measurement is defined         as a SSB based intra-frequency measurement provided the center         frequency of the SSB of the serving cell indicated for         measurement and the center frequency of the SSB of the neighbour         cell are the same, and the subcarrier spacing of the two SSBs         are also the same.     -   SSB based inter-frequency measurement: A measurement is defined         as a SSB based inter-frequency measurement provided the center         frequency of the SSB of the serving cell indicated for         measurement and the center frequency of the SSB of the neighbour         cell are different, or the subcarrier spacing of the two SSBs         are different.

An SS block may be associated with a specific beam, e.g., SS block # x is transmitted via beam # y.

SUMMARY

As a part of developing embodiments herein a problem of the bitmap solution will first be identified and discussed.

Some of the SS blocks within an SS burst set may actually be not transmitted at pre-defined locations. The UE may be aware of the actually transmitted SS blocks of the serving cell but not of other cells, while the other cells even on the same carrier frequency but also on a different carrier frequency may have a different set of the actually transmitted SS blocks which the UE is currently not aware of. Furthermore, SS block burst sets may be transmitted on multiple frequency for the same cell (which sometimes is also described as multiple SS blocks per cell).

-   -   It is currently unclear what is the set of actually transmitted         SS blocks in case of multiple SS blocks per cell     -   When identifying or measuring neighbour cells, if the UE is not         aware of the actually transmitted SS blocks, the UE has to         blindly or semi-blindly detect all SS blocks, while going         through all candidate SS block locations within the 5 ms window.         Transmitted SS blocks may still be not detected by a UE due to         low signal level (e.g., if the SS block is transmitted via a         beam pointing in an opposite direction) but attempting to detect         SS blocks that are not transmitted is a waste of UE resources         and time, which is especially critical when the number of SS         blocks may be large, e.g., up to 64 in the higher frequency         range. Furthermore, the UE would need to do this for each cell         to measure, intra-frequency or inter-frequency, since the UE         cannot assume the same SS block pattern in all cells.     -   A BS serving the UE is not aware of the SS block transmission         pattern or beam transmission pattern of a neighbour BS. Hence,         some settings in the measurement configuration that the serving         BS may set that may be a function of number of beams in         detectable neighbour cells cannot be properly tuned by the         serving BS, such as maximum number of beam measurement         information to be reported per cell, maximum number of beam         measurements for cell quality derivation, etc. Neither the BS         may assist the UE in identifying or measuring neighbour cells,         e.g. to reduce the UE complexity and make the         measurements/detection faster     -   Currently the UE cannot receive the information about actually         transmitted SS blocks from a core network, e.g., a positioning         node, when performing positioning measurements.     -   A core network node (positioning node) is not aware of the         transmission pattern of SS blocks or beams of a radio BS which         are transmitting radio signals that may be used for positioning,         and hence cannot assist the UE in making it aware of which SS         blocks are actually transmitted or not when the UE is requested         to perform positioning measurements involving neighbour cell.         Therefore, prior to performing a positioning measurement, the UE         first have to correctly detect the signal which is complex at         low signal quality when the UE needs to measure on many         neighbour cells (e.g., in LTE, the UE shall be able to perform         measurements down to −13 dB).

DETAILED DESCRIPTION

According to a first embodiment, a first network node, e.g., a first Base Station (BS) provides or indicates to a second network node, e.g., a second BS, a core network node, and/or a positioning node, an SS block or beam configuration comprising one or a group of patterns indicative of which SS blocks or beams transmitted by a third network node, e.g., the first BS or a third BS, are:

-   -   actually transmitted and/or actually not transmitted, e.g., a         transmission pattern, and/or     -   available and/or not available for UE measurements e.g., a         measurement pattern which is always either the same or a subset         of the transmission pattern, i.e., an SS block or beam cannot be         measured if it is not transmitted. E.g., some SS blocks or beams         may be transmitted but subject to high interference or may be         not suitable for the UE measurements for some other reason.

Thus according to the first embodiment, the first network node, provides or indicates to a second network node, an SS block or beam configuration comprising one or a group of patterns indicative of which SS blocks or beams transmitted by a third network node, are⋅actually transmitted and/or actually not transmitted, and/or⋅available and/or not available for UE measurements.

The actually transmitted SSBs or SSBs available for measurements may be per frequency or per cell.

Or there may be a combination of per frequency indication of SSBs and additional per cell indication of SSBs.

According to another, embodiment, the first network node receives from a UE, the SS block or beam configuration comprising one or a group of patterns indicative of which SS blocks or beams that are transmitted by a third network node.

Embodiments herein may provide the following advantages:

By knowing the SSB and/or beam configuration, (e.g. the number of transmitted 35 beams, nominal SSB position being used, etc.) for a given cell and/or cells in a given measurement object, a serving BS such as a network node may configure the UE with proper beam related parameters such as maximum number of beam measurements to be averaged for cell quality derivation or maximum number of beams to be reported, etc.

A measurement object when used herein e.g. means a Radio Resource Management (RRM) measurement related network configuration to the UE which describes e.g. target frequency to measure and certain assisting information for perform the measurements.

UE complexity and resource consumption may be significantly reduced if the network informs the UE about actually transmitted SS blocks in neighbour cells.

Some of the example embodiments herein relates to Methods for Managing SS Block Configuration of Neighbour Cells.

Communicating the SS block and beam configuration.

Between Network Nodes

According to some first embodiments, the first network node 111 (e.g., a first BS) obtains and e.g. provides or indicates to the second network node 112 (e.g., a second BS, a core network node, positioning node) the SS block or beam configuration comprising one or a group of patterns indicative of which SS blocks or beams transmitted by a third network node 113 (e.g., the first BS or a third BS) are:

-   -   actually transmitted and/or actually not transmitted (e.g., a         transmission pattern), and/or     -   available and/or not available for UE measurements (e.g., a         measurement pattern which is always either the same or a subset         of the transmission pattern, i.e., an SS block or beam cannot be         measured if it is not transmitted; e.g., some SS blocks or beams         may be transmitted but subject to high interference or may be         not suitable for the UE measurements for some other reason).

Thus according to the first embodiment, the first network node 111, provides or indicates to a second network node 112, an SS block or beam configuration comprising one or a group of patterns indicative of which SS blocks or beams transmitted by a third network node 113, are⋅actually transmitted and/or actually not transmitted, and/or⋅available and/or not available for UE measurements.

In one example, the third network node 113 may be the same as the first network node. In another example, the third network node 113 may be different from the first and the second network node 112, in which case the first network node 111 may forward (e.g., transparently or not-transparently to the first network node), relay or retransmit the above configuration to the second network node 112.

The configuration may also indicate the actual SS block transmissions about which the first network node 111 is certain about, e.g., SS block #0, #1, and #3 in the example in above when the determining of the configuration for the third network node 113 is based on UE measurements.

Some more examples of the first, second, and third network nodes 111-113 are BS, relay, a core network node, e.g., Operation and Maintenance (O&M) or Self-Organizing Network (SON), positioning node, e.g., sending the configuration:

-   -   from BS or relay to BS, e.g., via Xn interface,     -   from BS or relay to relay,     -   from BS or relay to core network node,     -   from BS or core network node to positioning node,     -   from core network node to positioning node,     -   from serving BS to handover target BS,     -   from serving BS to core network node or positioning node.

In some embodiments, the configuration may be UE specific or associated with UE specific context. This is helpful, e.g., at handover since it may make the target BS aware of the configuration of specific SS blocks configured for UE measurements in the old BS, especially when multiple, e.g. at different frequencies, SS blocks may be transmitted in a cell.

In another embodiment, the configuration may be cell-specific and not associated with any specific UE, e.g., when no multiple SS blocks are transmitted in a cell or when the same pattern of the actually transmitted SS blocks is configured for all frequencies in a cell when multiple SS blocks are transmitted in the cell.

In yet another embodiment, the information such as the configuration is associated with a cell but also with a frequency, e.g., allowing different patterns of the actually transmitted SS blocks at different frequencies in a cell when multiple SS blocks are transmitted in a cell.

There may be a “request message” from the second network node 112 to the first network node 111 indicating that the second network node 112 wants to know the SSB and/or beam configurations associated with the cells and/or frequencies of the first network node 111.

-   -   That “request message” may also comprise one or multiple         Physical Cell Identity (PCI)s so that the first network node 111         knows for which PCI or Cell Global Identity (CGI) and/or         frequency the second network node 112 wants to know the SSB         and/or beam configuration;     -   That “request message” may also comprise one or multiple         measurement objects so that the first network node 111 knows for         which measurement objects the second network node 112 wants to         know the SSB and/or beam configuration;     -   That “request message” may also comprise a combination of one or         multiple measurement objects and/or PCIs or CGIs so that the         first network node 111 knows for which measurement objects         and/or PCIs or CGIs and/or frequency the second network node 112         wants to know the SSB and/or beam configuration.

There may be a “response message” from the first network node 111 to the second network node 112 indicating the SSB and/or beam configurations per PCI or CGI and/or frequency.

-   -   That may be done for all measurement objects associated to that         first network node 111 or only to a subset.     -   That may be done for all PCIs or CGIs and/or frequencies         associated to that first node or only to a subset.     -   That may be done for combinations of measurement objects and/or         PCIs or CGIs and/or frequencies associated to that first network         node 111 or only to a subset.

There may be an “update request message” from the second network node 112 to the first network node 111 indicating that the second network node 112 wants to obtain the SSB and/or beam configurations updates associated with the cells and/or frequencies of the first network node.

-   -   That “update request message” may also comprise one or multiple         PCI or CGI and/or frequencies so that the first network node 111         knows for which cell and/or frequency the second network node         112 wants to know the SSB and/or beam configuration;     -   That “update request message” may also comprise one or multiple         measurement objects so that the first network node 111 knows for         which measurement objects the second network node 112 wants to         know the SSB and/or beam configuration;     -   That “update request message” may also comprise a combination of         one or multiple measurement objects and/or PCIs or CGIs and/or         frequencies so that the first network node 111 knows for which         measurement objects and/or PCIs or CGIs and/or frequencies the         second network node 112 wants to know the SSB and/or beam         configuration.

There may be an “update message” from the first network node 111 to the second network node 112 indicating the SSB and/or beam configurations per PCI or CGI and/or frequency has changed:

-   -   That may be done for all measurement objects associated to that         first network node 111 or only to a subset.     -   That may be done for all PCIs or CGIs and/or frequencies         associated to that first network node 111 or only to a subset.     -   That may be done for combinations of measurement objects and/or         PCIs or CGIs and/or frequencies associated to that first network         node 111 or only to a subset.

In another embodiment, the SSB and/or beam configuration may be comprised in a handover-related message, e.g., the configuration in a serving and/or target cell.

Between UE 120 and Network Node

According to another embodiment, a first network node 111 receives from the UE 120 the SS block or beam configuration comprising one or a group of patterns indicative of which SS blocks or beams transmitted by a third network node 113.

Examples of the first network node 111 and/or third network node 113:

-   -   Serving BS and/or neighbour BS or any type of radio network node         transmitting SS blocks,     -   a core network node and/or BS or any type of radio network node         transmitting SS blocks,     -   a positioning node, e.g., Evolved Serving Mobile Location Center         (E-SMLC) or a like) and/or BS or any type of radio network node         transmitting SS blocks.

The UE 120 may obtain by e.g. determine and send and/or report the configuration in an unsolicited way or upon an explicit or implicit request from the first network node. The configuration may comprise an indication for each of all or of a subset of nominal SS block positions, indicative of that the corresponding SS block is actually transmitted or not. The subset may be requested by the first node or determined based on a pre-defined rule or condition or the signal strength or quality.

The obtaining such as determining may be based on UE measurements/detection attempts of SS blocks at nominal positioning from the third network node 113 or reading a message from the third network node 113, e.g., system information.

In one example, the UE 120 may send the obtained such as determined configuration to the first network node 111, which obtains the configuration by e.g. receiving it from the UE 120, when such configuration was not provided by the first network node 111 to the UE 120, e.g., in measurement configuration or system information.

In another example, the first network node 111 may explicitly request to determine the configuration, e.g., for any detected cell or for a specific cell (e.g., identified by cell identity).

In another example, a first network node 111 configures the UE 120 to detect the SS block pattern, i.e. number of SSBs being transmitted, nominal positions being used, etc., or beam configuration of at least one neighbour cell (e.g. by configuring the UE 120 with a PCI) and report to the first network node 111. One way to perform that configuration is by enhancing the CGI reporting configuration where the UE 120 is provided with a PCI. Based on that, the UE 120 obtains that SSB pattern and/or beam configuration. This may e.g. be performed by reading a system information message from the cell associated to the provided PCI.) The UE 120 sends a measurement report to the first network node 111, e.g. jointly with other information such as cell global identifier, core network information, PLMN information, etc. By having that information, the network may trigger the setup of an inter-node interface, e.g. Xn interface between gNodeBs. That configuration procedure towards the UE 120 may be triggered by the first network node 111 upon receiving a measurement report from the UE 120 associated to a given PCI and, by the first node identifying that it does not have stored information about that PCI regarding its SSB and/or beam configuration.

The word network when used herein may refer to any one or more of the first, second and third network node 111, 112, 113. The word network is used interchangeably with any one or more of the first, second and third network node 111, 112, 113.

When the UE 120 is attempting to detect SS blocks at all nominal locations and reports the results of this (e.g., the UE 120 may report a measurement for each successfully detected SS block and may not report for not detected SS blocks or may report a pre-defined value for not detected SS blocks indicative that the SS block at this nominal location has not been detected), an SS block may be not detected because it is not transmitted or because the signal quality is too low at the UE 120 location. By receiving such UE 120 results, the first network node 111 gets at least aware of the SS blocks that are transmitted for which the measurements are received. The first network node 111 may also combine the results from two or more UE 120 s to determine the actually transmitted SS blocks of a cell and/or at a frequency. Example:

-   -   The UE 120 detects and reports SS block #0 and SS block #3,         while another UE detects and reports SS blocks #1 for the same         cell and/or frequency, from which the first network node 111 may         conclude that at least SS blocks #0, #1, and #3 are transmitted,         while SS block #2 may still be uncertain and possibly may not be         transmitted by the third network node 113. The first network         node 111 may therefore configure UE measurements assuming that         SS block #2 is not transmitted.

In another embodiment, the SSB and/or beam configuration may be comprised in a handover-related message, e.g., the configuration of a serving and/or target cell, communicated to the UE 120 or communicated by the UE 120.

Yet another example embodiment comprises a combination of per frequency indication of present SSBs and/or SSBs to include in measurements and additional per cell indication of the previous mentioned is assumed. Information e.g. comprises A) an indication which SSB are present and which out of those should be taken into account in measurements per a frequency, sort of default value (this may be same as in other embodiments) additionally it has part B) same information but cell specific, list of cells that it applies but denotes more SSBs to be present and/or to be taken into account in measurements.

This means there may be two types of cells on the frequency, all fulfill the per frequency SSB indication but then some cells have more SSBs present. The network such as the first network node 111 or third network node 113 113 may indicate to UE 120 this information in the SSB timing configuration per frequency and the per cell SSB indication for the second timing configuration applicable for a list of cells.

The above mentioned A) and B) info may be given to the UE 120 as mentioned above. As priori art there is SSB timing per frequency, add there information A. Then there is SSB timing per list of cells (which has to fulfill per frequency timing but may have more SSB occasions) add here information B.

An SSB timing configuration may comprise, e.g., subframe number, radio frame number, slot number, an offset with respect to a reference time, e.g., with respect to SFNO or frame or subframe boundary.

Using the SS Block and Beam Configuration

Second Network Node 112 or First Network Node 111

The second network node 112 receives from the first network node 111 or the first network node 111 obtains by e.g. receiving from one or more UEs 120, the SS block or beam configuration. The second network node 112 or the first network node 111 manages the configuration of neighbouring cells, based on the received configuration by e.g. e.g. performing one or any combination of the below, based on the received configuration:

-   -   Sending all or a part of the received configuration to another         network node, e.g., a BS, a core network node, or a positioning         node.     -   Sending all or a part of the received configuration to one or         more UE 120 s (e.g., via broadcast, multicast or dedicated         higher layer or lower layer signaling), e.g., in the assistance         data for UE measurements or in the positioning assistance data         for UE 120 positioning measurements or determining UE 120         location.     -   Configuring measurement gaps (e.g., the measurement gap length         so that a measurement gap may cover all or a specific group of         the actually transmitted SSBs while minimizing within the gap         the number of SSBs which are not transmitted).     -   Configuring measurement cycles (e.g., so that a measurement part         of the measurement cycle may cover all or a specific group of         the actually transmitted SSBs)—used e.g. for measurements on         deactivated configured CCs.     -   Configuring DRX (e.g., to align DRX ON periods with the actually         transmitted SSBs).     -   Updating one or more measurement objects and/or reporting         configurations for one or more UE 120 s.         -   One parameter that may be updated is the maximum number of             beams N, in the measurement object (measObject) used to             derive cell quality e.g. by averaging N beam measurement             results. If the network knows that neighbour cells             associated to a given measObject-x only transmit K beams,             the network knows it should not configure the parameter N to             be higher than K.         -   Another parameter that may be updated is the maximum number             of beams X to be reported per cell and to apply L3 filter to             its measurements. If the network is aware that neighbour             cells associated to a given measObject-x only transmit K             beams, the network knows it should not configure the             parameter X to be higher than K. That helps the UE 120 to             know it should not setup more than K L3 filters for that             particular measurement object and/or cell.         -   In yet another example, the SSB and/or beam configuration of             a neighbour cell may be provided to the UE 120 to reduce the             UE 120 complexity and resource consumption, as well as to             shorten the measurement time.     -   Configuring the set of SSBs for measurements, e.g., mobility         measurements, Radio Link Monitoring (RLM), positioning         measurements, RRM measurements, SON measurements, Minimization         of Drive Test (MDT) measurements, etc.     -   Configuring measurement gaps for one or more UEs such as the UE         120 based on the received configuration. E.g., a first         measurement gap length and/or a first measurement gap         periodicity is configured if a first configuration is provided         and a second measurement gap length, and/or a second measurement         gap periodicity is configured if a second configuration is         provided.         -   E.g., shorter gaps may be used if a certain number of SS             blocks which are consecutive in time are not transmitted or             not available for UE measurements.     -   Configuring one or more own transmissions, e.g.,         -   Reducing the number of own SS block or beam transmissions at             times overlapping with the SS block or beam transmissions             indicated in the received configuration.         -   Changing the transmit power of own SS block or beam             transmissions at times overlapping with the SS block or beam             transmissions indicated in the received configuration, e.g.,             reducing the power to reduce the interference from the             latter or increasing the power to overcome the interference             from the latter.     -   Determining a common set of actually transmitted SSBs by all or         at least N cells in a set of cells, based on the information         about the actually transmitted SSBs for those cells.     -   Determining a common set of SSBs not transmitted by any cell in         a set of cells.     -   Determining a load characteristic or metric based on whether the         SSB is transmitted in a neighbour cell, e.g. neighbour         interfering cell, or not. E.g., the load is lower if it is not         transmitted and the load is higher if it is transmitted.

The UE 120

The UE 120 may use the obtained such as e.g. received SSB and/or beam configuration of a neighbour cell to adapt a measurement procedure, enhance receiver performance, or battery life, e.g. even more specifically any one or more out of:

-   -   Mitigate or cancel the interference from it, to enhance the         receiver performance when receiving signals from the serving         cell, or Total Radiated Power (TRP), or other neighbour cells,         or TRPs.     -   Avoid blind detection of whether the SSB is actually transmitted         or not.     -   Facilitate SSB-based measurements and reception of the system         information (e.g., PBCH which is also comprised in SSB) to         perform the measurements and receive the channels/signals that         are known to be transmitted.     -   Sending this information to another network node or another UE.     -   Adapting UE 120 activity pattern, e.g. no need to stay active         when none of the SSBs of interest is transmitted during a time         period (e.g., a slot or a subframe).     -   Switching the UE 120 receiver beam for receiving other signals         and/or channels in a different direction at the time when an SSB         is actually not transmitted.     -   A half-duplex UE 120 (e.g., HD-FDD) may transmit in UL or on a         side like, e.g. D2D or Vehicle-to-everything (V2X), if none of         the SSBs of interest is transmitted in a certain time unit and         thus no need to receive.     -   Switching to another carrier frequency when no SSBs of interest         are actually transmitted on a given carrier frequency.     -   Perform positioning measurements on the actually transmitted         SSBs in neighbour cells or neighbour frequencies.

Examples of SS Block and Beam Configuration

Further Extensions and Variations

With reference to FIG. 14, in accordance with an embodiment, a communication system includes a telecommunication network 3210 such as the wireless communications network 100, e.g. a NR network, such as a 3GPP-type cellular network, which comprises an access network 3211, such as a radio access network, and a core network 3214. The access network 3211 comprises a plurality of base stations 3212 a, 3212 b, 3212 c, such as the first second and third network node 111, 112, 113, access nodes, AP STAs NBs, eNBs, gNBs or other types of wireless access points, each defining a corresponding coverage area 3213 a, 3213 b, 3213 c. Each base station 3212 a, 3212 b, 3212 c is connectable to the core network 3214 over a wired or wireless connection 3215. A first user equipment (UE) e.g. the UE 120 such as a Non-AP STA 3291 located in coverage area 3213 c is configured to wirelessly connect to, or be paged by, the corresponding base station 3212 c. A second UE 3292 e.g. the UE 120 such as a Non-AP STA in coverage area 3213 a is wirelessly connectable to the corresponding base station 3212 a. While a plurality of UEs 3291, 3292 are illustrated in this example, the disclosed embodiments are equally applicable to a situation where a sole UE is in the coverage area or where a sole UE is connecting to the corresponding base station 3212.

The telecommunication network 3210 is itself connected to a host computer 3230, which may be embodied in the hardware and/or software of a standalone server, a cloud-implemented server, a distributed server or as processing resources in a server farm. The host computer 3230 may be under the ownership or control of a service provider, or may be operated by the service provider or on behalf of the service provider. The connections 3221, 3222 between the telecommunication network 3210 and the host computer 3230 may extend directly from the core network 3214 to the host computer 3230 or may go via an optional intermediate network 3220. The intermediate network 3220 may be one of, or a combination of more than one of, a public, private or hosted network; the intermediate network 3220, if any, may be a backbone network or the Internet; in particular, the intermediate network 3220 may comprise two or more sub-networks (not shown).

The communication system of FIG. 14 as a whole enables connectivity between one of the connected UEs 3291, 3292 and the host computer 3230. The connectivity may be described as an over-the-top (OTT) connection 3250. The host computer 3230 and the connected UEs 3291, 3292 are configured to communicate data and/or signaling via the OTT connection 3250, using the access network 3211, the core network 3214, any intermediate network 3220 and possible further infrastructure (not shown) as intermediaries. The OTT connection 3250 may be transparent in the sense that the participating communication devices through which the OTT connection 3250 passes are unaware of routing of uplink and downlink communications. For example, a base station 3212 may not or need not be informed about the past routing of an incoming downlink communication with data originating from a host computer 3230 to be forwarded (e.g., handed over) to a connected UE 3291. Similarly, the base station 3212 need not be aware of the future routing of an outgoing uplink communication originating from the UE 3291 towards the host computer 3230.

Example implementations, in accordance with an embodiment, of the UE, base station and host computer discussed in the preceding paragraphs will now be described with reference to FIG. 15. In a communication system 3300, a host computer 3310 comprises hardware 3315 including a communication interface 3316 configured to set up and maintain a wired or wireless connection with an interface of a different communication device of the communication system 3300. The host computer 3310 further comprises processing circuitry 3318, which may have storage and/or processing capabilities. In particular, the processing circuitry 3318 may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. The host computer 3310 further comprises software 3311, which is stored in or accessible by the host computer 3310 and executable by the processing circuitry 3318. The software 3311 includes a host application 3312. The host application 3312 may be operable to provide a service to a remote user, such as a UE 3330 connecting via an OTT connection 3350 terminating at the UE 3330 and the host computer 3310. In providing the service to the remote user, the host application 3312 may provide user data which is transmitted using the OTT connection 3350.

The communication system 3300 further includes a base station 3320 provided in a telecommunication system and comprising hardware 3325 enabling it to communicate with the host computer 3310 and with the UE 3330. The hardware 3325 may include a communication interface 3326 for setting up and maintaining a wired or wireless connection with an interface of a different communication device of the communication system 3300, as well as a radio interface 3327 for setting up and maintaining at least a wireless connection 3370 with a UE 3330 located in a coverage area (not shown in FIG. 15) served by the base station 3320. The communication interface 3326 may be configured to facilitate a connection 3360 to the host computer 3310. The connection 3360 may be direct or it may pass through a core network (not shown in FIG. 15) of the telecommunication system and/or through one or more intermediate networks outside the telecommunication system. In the embodiment shown, the hardware 3325 of the base station 3320 further includes processing circuitry 3328, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. The base station 3320 further has software 3321 stored internally or accessible via an external connection.

The communication system 3300 further includes the UE 3330 already referred to. Its hardware 3335 may include a radio interface 3337 configured to set up and maintain a wireless connection 3370 with a base station serving a coverage area in which the UE 3330 is currently located. The hardware 3335 of the UE 3330 further includes processing circuitry 3338, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. The UE 3330 further comprises software 3331, which is stored in or accessible by the UE 3330 and executable by the processing circuitry 3338. The software 3331 includes a client application 3332. The client application 3332 may be operable to provide a service to a human or non-human user via the UE 3330, with the support of the host computer 3310. In the host computer 3310, an executing host application 3312 may communicate with the executing client application 3332 via the OTT connection 3350 terminating at the UE 3330 and the host computer 3310. In providing the service to the user, the client application 3332 may receive request data from the host application 3312 and provide user data in response to the request data. The OTT connection 3350 may transfer both the request data and the user data. The client application 3332 may interact with the user to generate the user data that it provides. It is noted that the host computer 3310, base station 3320 and UE 3330 illustrated in FIG. 15 may be identical to the host computer 3230, one of the base stations 3212 a, 3212 b, 3212 c and one of the UEs 3291, 3292 of FIG. 14, respectively. This is to say, the inner workings of these entities may be as shown in FIG. 15 and independently, the surrounding network topology may be that of FIG. 14.

In FIG. 15, the OTT connection 3350 has been drawn abstractly to illustrate the communication between the host computer 3310 and the use equipment 3330 via the base station 3320, without explicit reference to any intermediary devices and the precise routing of messages via these devices. Network infrastructure may determine the routing, which it may be configured to hide from the UE 3330 or from the service provider operating the host computer 3310, or both. While the OTT connection 3350 is active, the network infrastructure may further take decisions by which it dynamically changes the routing (e.g., on the basis of load balancing consideration or reconfiguration of the network).

The wireless connection 3370 between the UE 3330 and the base station 3320 is in accordance with the teachings of the embodiments described throughout this disclosure. One or more of the various embodiments improve the performance of OTT services provided to the UE 3330 using the OTT connection 3350, in which the wireless connection 3370 forms the last segment. More precisely, the teachings of these embodiments may improve the data rate, latency, power consumption and thereby provide benefits such as user waiting time, relaxed restriction on file size, better responsiveness, extended battery lifetime.

A measurement procedure may be provided for the purpose of monitoring data rate, latency and other factors on which the one or more embodiments improve. There may further be an optional network functionality for reconfiguring the OTT connection 3350 between the host computer 3310 and UE 3330, in response to variations in the measurement results. The measurement procedure and/or the network functionality for reconfiguring the OTT connection 3350 may be implemented in the software 3311 of the host computer 3310 or in the software 3331 of the UE 3330, or both. In embodiments, sensors (not shown) may be deployed in or in association with communication devices through which the OTT connection 3350 passes; the sensors may participate in the measurement procedure by supplying values of the monitored quantities exemplified above, or supplying values of other physical quantities from which software 3311, 3331 may compute or estimate the monitored quantities. The reconfiguring of the OTT connection 3350 may include message format, retransmission settings, preferred routing etc.; the reconfiguring need not affect the base station 3320, and it may be unknown or imperceptible to the base station 3320. Such procedures and functionalities may be known and practiced in the art. In certain embodiments, measurements may involve proprietary UE signaling facilitating the host computer's 3310 measurements of throughput, propagation times, latency and the like. The measurements may be implemented in that the software 3311, 3331 causes messages to be transmitted, in particular empty or ‘dummy’ messages, using the OTT connection 3350 while it monitors propagation times, errors etc.
